perhaps, you’ve seen different types of espresso machines. the portafilter is a handle-like instrument that sticks out of the device. Sometimes referred to as group handle, portafilter plays its own important role in the espresso-making process.
This handle looks like a spoon and is the main tool for holding Ground coffee beans. portafilter has little notches that allow to lock it in the device during the process of extracting the espresso shot.
different types of espresso machines may have different models of the portafilter. they are similar in their function but are different in their design.
For example, the portafilter design for smaller espresso machines and larger machines is different. this is mainly to house the appropriate amount or volume of coffee ground in the portafilter basket.
In this article, we’ll have a look at the portafilter components and try to provide readers with the answers to the most frequently asked questions like:
- What does the portafilter do?
- What are the different types of portafilters?
- How can we use a portafilter?

portafilter anatomy
The main components that can be found in different types of portafilters are as follows:
Handle
You use the handle to secure the device onto the group head. Technically, the handle is not important for the process. But, for the user, the feeling of the touching handle is quite different with the professionally designed portafilter handles.
Basket
The basket is another part of the device. It is important for all types of portafilters and plays an important role in the volume of coffee grind that suits the device. This basket has holes that are below the device where the water will pass the grinds.
The basket in different models of portafilter may have some differences. For example, pressurized models use a mechanism in their baskets that creates additional pressure.
in these models, the mechanism for creating pressure works with a singular hole and is built into the portafilter basket.
Gauge
some models of portafilter have a gauge in their design. Especially in commercial portafilters, the importance of pressure gauges is more tangible. Because it allows users to check commercial machines’ pressure.
So, in the case that you do not have a gauge on the device itself, it is possible to check the output pressure of the machine pump by using this model.
Spring clip
This clip helps in keeping the basket. The spring clip is a long clip-like tool. It keeps the basket inside the portafilter by using a pressure mechanism. Note that by having the right spring clip, it will be easy to put the basket in and out of the device.
Spout
The main reason to use a spout is to help in flowing espresso out of the portafilter. Because it helps to flow more evenly. It is a unique component that is like a swoop. The spout is one of the main parts in some models. It can be single or double. This means, in some models, you have one spout and in others, there are two spouts.
Note that for having a double espresso shot at once, it is necessary to have two spouts.
in another word, it is easier to serve more cups of coffee to several people. This component is attached to the portafilter bottom.
We will mention that if your portafilter does not have a spout, it means that you have a “bottomless portafilter”.
What does the portafilter do?
Actually, by attaching a portafilter to the group head, you can extract espresso. It’s a simple device with simple components.
When hot water comes in contact with the grind coffee, it can provide us with tasty espresso shots.
What are the different types of portafilters?
All models of portafilters have the same function. But, it is important to note that each model may work in a slightly different way. This difference is due to the fact that different manufacturers may produce different models with unique designs.
The main difference in the function of the device is in the basket design. In fact, the hole size and pattern play an important role in the way that portafilter works.
Pressurized portafilter
This model creates additional pressure. This pressure mechanism is the main reason for its naming.
This model is suitable for beginners as it makes more pressure in the brewing process. So, if you don’t want to solely rely on coffee grind size and consistency of tamping, to provide the right amount of pressure, the mechanism in pressurized models will help you to extract espresso.
Note that different brands may use different pressure mechanisms. In some brands, the mechanism is built into the portafilter baskets. In others, the pressure mechanism is built into the machine itself.
It is worth mentioning that some models give you the ability to put pressure on or off (just by removing the mechanism for espresso pressurization).
Non-pressurized models
These models usually rely on the dosage, evenness, and size of grind coffee. Then, the user can create a suitable amount of pressure. Here, the brewing process is different from what we have in pressurized models.
So, in this model, we do not have an additional pressurization mechanism. Just by tamping down coffee, the pressure will be created for the brewing process.
As an experienced user, you may prefer this model. Because it allows you to extract espresso more craft fully.
Bottomless models
Bottomless portafilters are spoutless models. These models are also referred to as naked models. They give naked extractions or espresso shots.
Not having bottom portions mean that naked portafilters are great models for some highly experienced craftsmen to use their own unique techniques for espresso extraction.
The problems when using naked models is apparent. Because you can see the coffee is coming through the spout.
Remember that for using bottomless porta filter models, it is important to use high-quality grinders. Because high-quality grinders will give you better control over the grind size.
Pod portafilter models
Using prepackaged pods for espresso making led to emerging of pod portafilters in commercial and home applications.
It is a kind of portafilter that can be used by a pre-packed pod. Usually, in this model, E.S.E pod is used (this expression is an abbreviation for “easy serving espresso” pod).
It is worth mentioning that most pod portafilter models are pressurized models. For this reason, it is evident that these models are easy-to-use portafilters that are more suitable for beginners.
Note: to make the currently in-use machines more pod friendly, some ordinary people use portafilter adapters.
How do you use a portafilter?
Putting the grind inside the portafilter
First, you need to fill the portafilter basket. It’s important not to compress the grounds and to let the ground to loosely overfill the device. Then, make the grounds even at the top device and level it off.
Compress the coffee grinds
By using the tamper, try to compress the grinds. Typically, there is a line to know how deep to compress the coffee grinds.
Lock it and start the machine
You have to lock the portafilter. Then, depending on the type of machine you use, start extracting the espresso shots.
Repeat and adjust the machine
If the espresso shot did not come in the way you expected, it’s a good idea to repeat the process and do some adjustments.
By trying the process several times and doing the required adjustment, it is possible to learn more about crafting the process (by considering important factors like grind coarseness and size).
Final word
Finally, we have to thank you for reading this text. Remember if you’re interested in having the best espresso shots, there is no way to become a pro! except you make your hands dirty and try the process for times. We hope that you make the process to the end and become a portafilter professional.
